This is a large poster. Jim Walsh has used this analysis for decades to train educators on the proper implementation of federal law. Now, in an easy reference chart, this analysis can be readily available to any educator. Perfect for all school administrators. This title is a laminated and poster sized. Students in Ouadrant One do not have a disability and do not need specially designed instruction. Students in Quadrant Two are those who have disabilities that do not require the provision of specifically designed instruction. These students are entitled to accomodation under Section 504 and the ADA. Students in Quadrant Three are those who require a good deal of special instruction, but for reasons other than a disability. Students in Quadrant Four must 1) have a disability and 2) as a result of the disability, need special education services.
